Soundtrack

A soundtrack, also written sound track, can be recorded music accompanying and synchronized to the images of a motion picture, book, television program or video game; a commercially released soundtrack album of music as featured in the soundtrack of a film or TV show; or the physical area of a film that contains the synchronized recorded sound.

Origin of the term

In movie industry terminology usage, a sound track is an audio recording created or used in film production or post-production. Initially the dialogue, sound effects, and music in a film each has its own separate track (dialogue track, sound effects track, and music track), and these are mixed together to make what is called the composite track, which is heard in the film. A dubbing track is often later created when films are dubbed into another language. This is also known as a M & E track (music and effects) containing all sound elements minus dialogue which is then supplied by the foreign distributor in the native language of its territory.
